How to use the advanced tools

Fees are only the start. Ads, returns, and VAT decide whether a “cheap” platform still pays.

Model real drag

Add promoted listing % and return rate so the ranking matches what you actually keep.

Price from the floor up

Use break-even to set a minimum price per platform before you draft the listing.

Stress-test A vs B

Compare a higher price with ads against a quieter organic listing — then share the link.
